My views on the selection of coal coking processes

Thread Content

In my opinion, when choosing the coal coking process, several factors should be taken into consideration: 1. Select an appropriate process based on the raw coal: (1) The stable type of coal that can be guaranteed by the raw material supplier； (2) Can it suit local coal types ； 2. Selection based on the maturity level of coal-to-liquid technologies: (1) Mature technologies: Involving high initial investment (slurry coal, Shell), suitable for companies with substantial financial resources ； Low investment options (fixed-bed, Ruchi) suitable for small and medium-sized enterprises ； But in terms of **policies and return rates, it’s still better to make a higher investment once ； (2) Process in the experimental phase: These processes (with space furnaces as a typical example) are only suitable for large state-owned chemical and petrochemical enterprises, as they involve a high degree of unpredictability and there is a risk of experimental failure; for private enterprises, this would mean risking their very existence. 3. Based on the situation of coal processing technicians: (1) Mature technology: There are many technicians with extensive experience, resulting in a high probability of stable production operations ； (2) Pilot stage process: Technicians have to gain experience from scratch, and production cannot operate stably for a period of time. Due to my lack of thorough consideration, there are still many factors to take into account. Please give me some advice. Our company is a private enterprise, and we want to install a gasification unit. We have two options: coal water slurry or a space furnace. In my opinion, it’s safer to choose coal water slurry. After all, for a private enterprise, funding is a major issue. If we opt for a space furnace, it may take several years before operations can start normally, and the losses during that time could be substantial; in worst cases, the company might even go bankrupt.
